Question
Part II (50 points, each problem is worth 5 points) Write SQL queries for the following database: id Customers name email id Categories name Ho Ho 8 Orders id customer_id B id Products category_id name price но HO Order_Product id order_id product_id quantity 1. Display all customers whose email is null or ends with 'fiu.edu' or 'gmail.com' 2. Display the number of orders placed by a customer whose name is ‘Jason Bourne' (assume there is only one customer with this name). 3. Insert a new product (category_id = 1, name = 'apple', price = 3.00) into the product table. Assume Products.id has a default value. 4. Create the Order_Product table as follows: id is the primary key and its data type is serial, quantity is an integer which doesn't allow null, order_id and product_id are foreign keys and will be set to null on delete. 5. Display the average price of all the products. For example, there are only three products in the database with a price of 7, 8 and 9. Then the average price would be 8. 6. Display all categories with the number of products in them. Note that categories with no products in them also need to be listed, with the number equals to 0. An example output: category_name Books Phones Clothes total_products 60 7 15 0 7. Display the total sales amount (the sum of all orders' total amount). For example, there're only two orders in the database. One order bought 2 iPhones with a unit price of 10, the other order bought 5 iPads with a unit price of 8. Then, the total sales amount would be 2*10 + 5*8 = 60. An example output: sale_amount
